How does this stuff hold up? Can you wash your car often with it looking new(ish). Can it be removed with no damage to the car. Any advice would be cool.

My 3M gloss black roof wrap has worked out fine so far despite the workmanship a step down from top notch. Before the wrap everyone said that gloss black would accumulate micro scratches/swirls real easy after constant washing and scrubbing. So far wax has proved to be a very useful tool for keeping the shine on. As for reversing to stock color, the wrap will not damage the finish, you can pretty much just pull it off.
